5 GHz doesn't work for me.

For adding my device I made the following patch:

This patch is derived from http://wikidevi.com/files/Drivers/Realtek/rtl8812AU_8821AU_linux_v4.2.2_7502.20130517_addl_IDs_added.tar.bz2

However, 5 GHz mode doesn't work for me. Any ideas?

[JSkier21]

Interesting, it always seems to work for me no matter what machine I'm on. What kernel are you compiling against? Also, what device (not that it should matter)?

I ask because initially I was compiling on -ck patchset and 5 ghz wasn't working, however vanilla kernel everything is great (3.16.2).

I think the main problem was I used the wrong driver, if I remember
correctly.. I could solve the problem somehow.

I am on Fedora 21 Workstation x86_64 and 5Ghz does not work for me. As in, I can see my 5Ghz network, but connection fails.

some output from dmesg

[bits3rpent]

I am using Alfa's AWUS036AC http://www.alfa.com.tw/products_show.php?pc=134&ps=208 on a usb 3.0 port using a docking cradle

[bits3rpent]

Using an ASUS AC56 Wireless Adapter, 5Ghz worked

[bits3rpent]

Actually now 5Ghz is not working again on either -___- definitely not my router, literally every device that I have that runs at 5Ghz is working fine.
EDIT: as I posted it 5Ghz worked again.

It works occasionally on my ASUS AC56 I guess.

[bits3rpent]

Great, working again. There seems to be no rhyme or reason to it working or not. https://mega.co.nz/#!rVUiAYiJ!6vpJra9s8LnexQ92i5NF0YsgCKPM4C4-Z195f46btMk
Is the output of dmesg.

[hitam4450]

The driver compiles without errors, 5 GHZ network is visible, but cannot connect !

Why?????
